I am currently reading The Good News We Almost Forgot: Rediscovering the Gospel in a 16th Century Catechism, by Kevin DeYoung.
Here is a quote from the book:
"...it doesn't help much to know all about comfort and joy if we don't know what is required to live and die in this comfort and joy. Belonging to Jesus and not ourselves means knowing three things: guilt, grace, and gratitude...First, we understand our sin. Then we understand salvation. And finally we understand how we are sanctified to serve.
"All three things are necessary. If we don't know about our sin--which brings a true sense of guilt--we will be too confident in our abilities to do right and make the world a better place. We will ignore our most fundamental problem, which is not lack of education, or lack of opportunity, or lack of resources but sin and its attendant misery. But if we don't know how we are set free from this sin and misery--...through God's grace--we will try to fix ourselves in futility or give up altogether in despair. And if we don't know how to thank God, showing gratitude for such deliverance, we will live in a self-centered, self-referential bubble, which is not why God saved us from our sin and misery in the first place. If Christians would hold to all 'three things' and not just one or two, we would be saved from a lot of poor theology and bad ideas." Kevin DeYoung
"If you obey my commands, you will remain in my love, just as I have obeyed my Father's commands and remain in his love. I have told you this so that my joy may be in you and that your joy may be complete." John 15:10-11
"Praise be to the God and Father of our Lord Jesus Christ, the Father of compassion and the God of all comfort, who comforts us in all our troubles, so that we can comfort those in any trouble with the comfort we ourselves have received from God. For just as the sufferings of Christ flow over into our lives, so also through Christ our comfort overflows."
2 Corinthians 1:3-5
